Question

我正在用这个把头发扯掉。我在带有嵌套资源的form_with上获得了不允许的参数。我正在使用Rails 5.2.1和Ruby 2.5。

我不确定这是哪里出了问题。我尝试过各种site_params的变体，但是没有运气。任何帮助将不胜感激。

这是我的路线。rb：

resources :locations do
    post 'sites', to: 'sites#custom_create', as: :site_custom
    resources :sites, except: [:edit, :update, :show]
  end

以及相关的控制器功能：

  def new 
    verify_site_name or return
    @site =  @location.sites.new
    authorize @site
    @available_site = AvailableSite.find_by(site_name: params[:site_name])
    @finder_results = get_finder_results([:site_name], @location)
  end

  def create
    verify_site_name or return
    @site = @location.sites.new(site_params)
    authorize @site
    respond_to do |format|
      if @site.save
        format.html { redirect_to location_sites_path, notice: 'Location was successfully created.' }
        format.json { render :show, status: :created, site: @site }
      else
        format.html { redirect_to location_sites_path, alert: "#{@site.errors.full_messages.first}" }
        format.json { render json: @site.errors, status: :unprocessable_entity }
      end
    end
  end


# Never trust parameters from the scary internet, only allow the white list through.
    def site_params
      params.permit(:location_id, :place_id, :site_name, :review_url)
    end
    # Use callbacks to share common setup or constraints between actions.
    def set_site
      @site = Site.find(params[:id])
    end
    def set_location
      @location = Location.friendly.find(params[:location_id])
    end

当然还有表单本身：

<%= form_with(model: [@location, @site], local: true, class: 'site-form') do |form| %>
      <%= hidden_field_tag(:site_name, @available_site.site_name) %>
      <div class="field md:w-3/4 lg:w-2/3 mx-auto text-left">
        <%= form.text_field :review_url, class: 'text-input',  placeholder: 'https://www.facebook.com/yourbusinessname/review/?ref=page_internal'  %>
        <span class="form-required">*required</span>
      </div>
      <%= form.submit "Manually Submit #{@available_site.site_name.titleize}", class: 'btn btn-green btn-outline' %>
    <% end %>

最后是日志：

Answer 1

尝试：

def site_params
  params.require(:site).permit(:location_id, :place_id, :site_name, :review_url)
end

site的参数嵌套在params[:site]中。您应该首先从所有参数中删除此哈希，然后在其上调用permit。现在，您正在清理所有参数（包括您显然不感兴趣的某些内容，例如utf8或authenticity_token）。

不允许的参数：：utf8，：authenticity_token-Rails 5.2 form_with
